These days, it seems you've got problems to deal with running any XHTML
document (valid or not) through a validating XML 1.0 parser. You've got even
bigger problems running a namespace document through.

I can't say I'm an expert in validation, but I do know that RSS takes this
approach, and we have schemas in Schematron, Examplotron, RELAX (coming
soon), and a bunch more I can't remember. I'm sure other namespaced formats
do this and work too.
